This sounds like you need to trim the fiberglass flange down a bit in the areas where the seal is being split. Some cars have a "tall" flange on the underbody, and this can lead to overcompression of the seal. You can trim off up to about a quarter inch, reinstall the seal, and see if this problem continues. Careful not to trim so much that the seal has nothing to grip to. One way to be a little more "scientific" about it is to remove the seal, apply some lumps of modeling clay to the door surface that normally touches the seal, and then close the door. Then, open it back up, and measure the clay thickness. I think that you will find that it gets very thin in the problem areas, and remains thicker elsewhere. Simply trim the fiberglass to get a consistent gap. Remember to let everybody on the List know what you find, so that we can learn from your experience.

This happened now on both sides, as well as the rear corner from the roof down. The seals seem to just split down the middle-I am wondering if this is a door adjustment, or is this just something I will have to deal with every time. My seals were new before this happens-what gives?-#5003
